Use git rev-parse --symbolic-full-name to get the HEAD target ref

Browse source 
This will prevent us trying to depend on a file that doesn't exist in
case someone goes on a detached HEAD. For example, this could happen
during a bisect.

  (detached head) $ git rev-parse --symbolic-full-name HEAD
  HEAD
  (master) $ git rev-parse --symbolic-full-name HEAD
  refs/heads/master

This will break on a packed ref, though.
